CENTRAL KITSAP — Wheeled vandals destroyed the upper field at Anderson Hill, making it unavailable to soccer teams until April.

Overnight Sunday, somebody drove a quad down a steep bank from Impasse Road and between two metal posts designed to block wider vehicles, said Kitsap County Parks Superintendent Dori Leckner. Reaching the grass, they spun doughnuts and figure eights, leaving up to 6-inch-deep ruts.

Nobody saw or heard the vehicle, but it was determined to be a quad from the tracks and wheelbase, said Leckner, who was amazed it didn't roll when it descended the 45-degree bank.

"They knew what they were doing and had an objective, and the object was to do doughnuts and tear it up," she said.

The county will lose more than $5,000 in rental income. The season is winding down, Leckner said, though the FC Crush soccer club had been approved to play there for the first time this winter because the field was in such good shape. Other clubs also use the field.

Repair costs are estimated at about $650 for staff labor, $300 for sand and $300 for grass seed, she said. Large rocks will be brought in from another park to use as a barrier.

Anybody with information is asked to call the Kitsap County Sheriff's Office at 360-337-7101.
